Python: Remove unwanted characters from a given string
Python String: Exercise-89 with Solution
Write a Python program to remove unwanted characters from a given string.
Sample Solution:-
Python Code:
def remove_chars(str1, unwanted_chars):
for i in unwanted_chars:
str1 = str1.replace(i, '')
return str1
str1 = "Pyth*^on Exercis^es"
str2 = "A%^!B#*CD"
unwanted_chars = ["#", "*", "!", "^", "%"]
print ("Original String : " + str1)
print("After removing unwanted characters:")
print(remove_chars(str1, unwanted_chars))
print ("\nOriginal String : " + str2)
print("After removing unwanted characters:")
print(remove_chars(str2, unwanted_chars))
Sample Output:
Original String : Pyth*^on Exercis^es After removing unwanted characters: Python Exercises Original String : A%^!B#*CD After removing unwanted characters: ABCD

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
